Positive correlation between negative urgency and [AcO>SO] BOLD activation in Left and Right vmPFC. Positive correlation between mean [AcO > SO] BOLD activity as extracted (height threshiold p < 0.001) from the left vmPFC (red box) and right vmPFC (blue box) with negative urgency (NUR). For reference, the inset shows a voxel-wise map of the correlation between [AcO > SO] and NUR in voxel-wise analysis (display threshold, p < 0.05; masked for [AcO > SO] activation).
